UNIFIED TRANSMISSION CONFIGURATION INDICATOR STATE INDICATION
A wireless device and a base station may use resources for wireless communications. One or more unified transmission configuration indicator (TCI) state(s) may be indicated using a parameter, field, message, and/or signaling. The unified TCI state(s) may be associated with physical uplink control channel (PUCCH) resource (or a PUCCH resource group). The unified TCI state(s) may be applied for communications, via the PUCCH resource, between the wireless device and the base station for which at least two unified TCI states may be activated. The unified TCI state(s) may be associated with control resource set (CORESET). The unified TCI state(s) may be applied for communications, via the CORESET, between the wireless device and the base station for which at least two unified TCI states may be activated. The unified TCI state may be indicated by downlink control information (DCI) scheduling reception of a physical downlink shared channel (PDSCH) signal. The unified TCI state(s) may be applied for communication, of the PDSCH signal, between the wireless device and the base station for which at least two unified TCI states may be activated. The unified TCI state may be associated with a reference signal resource (or a reference signal resource set). The unified TCI state may be applied for communications, via a reference signal of the reference signal resource set, between the wireless device and the base station for which at least two unified TCI states may be activated. Communication described herein may be performed without requiring additional signaling to configure parameters for such communication.

A wireless device may be configured with resources to communicate with a base station. At least two transmission and reception points may be used to transmit one or more repetitions using resources, such as sounding reference signal (SRS) resources. Repetition may be prioritized over single transmission based on availability of the resources. For example, transmission of a lower priority type of information configured with resources for repetition may be prioritized over transmission of a higher priority type of information that is configured with resources for only a single transmission, such that increased utilization of repetition may be achieved.
Systems, apparatuses, and methods are described for message classification and management. A message may indicate a request for placement of a content item, such as an advertisement or advertisement campaign, into one or more content streams. A message ID associated with the message may be converted to a bit vector to compare to one or more filter data sets. The comparison of the bit vector to the filter data sets may determine whether the message may correspond to a previous message, such as a previous advertisement or advertisement campaign. The message may be classified as a new message or an update message.
Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or in a different frame. The reference block may be indicated by a block vector (BV). The BV may be encoded as difference between a block vector predictor (BVP) and the BV. The BVP may be adjusted to improve prediction accuracy of the BVP.

TIMING ADVANCE REPORTING IN NON-TERRESTRIAL NETWORKS
Timing advance (TA) reporting may be used in wireless communications. TA reporting information may be provided by a wireless device to align timing between the wireless device and a base station, such as in a non-terrestrial network. TA reporting information may be sent via a scheduling report (SR) procedure, a buffer status report (BSR) procedure, and/or a random access (RA) procedure. To avoid unnecessary transmissions of TA reporting information, TA reporting may be canceled based on one or more of a receipt of a timing offset and/or an expiration of a timer.
The present disclosure relates to methods and devices for display processing including an apparatus, e.g., a display processor. In some aspects, the apparatus may store one or more pixel conversion factors for at least one display panel. The apparatus may also determine whether to switch from a previous frame refresh rate to an updated frame refresh rate at the at least one display panel. Additionally, the apparatus may identify, upon determining to switch from the previous frame refresh rate to the updated frame refresh rate, a pixel conversion factor of the one or more pixel conversion factors associated with the updated frame refresh rate.

The at least one resource may be different from resources used in the connected state.
A base station and/or a wireless device may communicate using a plurality of transmission beams. Multiple transmission beams may be used for transmission such that a message may be sent via different transmission beams. Multiple transmission beams may be used for sending multiple repetitions of the message or for sending different portions of the message.
Data may be communicated during a connected state of the wireless device using configured resources. The wireless device may transition to an inactive state and/or an idle state. A release message, for transitioning the wireless device from the connected state, may indicate resource information for the wireless device to use to be able to send and/or receive data in the inactive state and/or in the idle state.
Wireless communications may use one or more devices for transmission and/or reception that may lead to potentially harmful exposure. One or more safety measures may be used for wireless communication devices, such as maximum power exposure (MPE) reporting and/or related operations. A time window may be used to detect a quantity of exposure instances. A message may be sent indicating exposure, for example, based on a quantity of exposure events during the time window satisfying a threshold. An MPE report may be sent based on MPE detection and one or more messages, such as for cell activation, bandwidth part (BWP) or other wireless resource activation and/or switching, and/or a discontinuous reception (DRX) or other state transition. An MPE report may be on a per-panel basis using a power headroom report (PHR) such that a panel-specific MPE report may be kept pending until sent in a PHR report.

A downlink control information (DCI) corresponding to one of the first RNTI or the second RNTI may be received. The DCI may be validated, at least based on a cyclic shift value associated with the DCI, if the DCI corresponds to the first RNTI. Otherwise, the DCI may be validated without considering the cyclic shift value. One of the first SPS or the second SPS, corresponding to the DCI, may be activated in response to the validating being successful.
Systems for distributed controlled access to data stored across a plurality of sources are disclosed. A plurality of content providers maintain user databases.

Abstract
A content adaptation method includes: obtaining a primary metadata profile associated with a particular time point of primary content; obtaining secondary metadata profiles each associated with corresponding secondary content of a plurality of secondary content; identifying one of the plurality of secondary content associated with a secondary metadata profile having a desired similarity value with the primary metadata profile associated with the primary content; and matching the identified secondary content with the particular time point of the primary content.
A computing device may be configured to provide authorization to a first content source to provide first content to a user device. The computing device may receive a request from the first content source to identify a location of second content to be presented to the user device and respond to the request by providing an address to the first content source. At the provided address, a request for the second content from the user device may be received. When responding to the request, the computing device may retrieve information associated with the user (e.g., user preference information) from the user device. Using this information, the computing device may generate at least one parameter for selecting the second contend and send a response to the user device. The response may include an address for the second content and the at least one parameter for selecting the second content.
Aspects of the disclosure relate to routing queries to a network repository and load balancing in a network. For a network repository having a plurality of content storage sites, relative replication latency of data among a pair of content storages sites can be monitored. Data indicative of such replication latency can be distributed among the content storage sites and can be provided, for example, to a network node in a system layer. A traffic and control manager can determine routing pathways for queries based at least in part on the relative replication latency data and performance conditions of network nodes.
The features relate generally to acquiring, formatting, and distributing video content to a variety of devices in multiple geographies. Some features described herein relate to preserving the stereoscopic effect for the formatting and distribution of 3D video content. Additionally, features described herein relate to customized and/or dynamic generation of a 3D stream based on a user device and/or user preferences.
A modem system may include modems that have multiple upstream transmitters for transmitting signals upstream in a communication network. In some embodiments herein, one or more of those upstream transmitters may be retasked to transmit downstream signals for reception at devices within a modem's premises. The downstream signal may be modulated differently from its original modulation as received by the modem, and may be modulated in a manner that can be received by legacy components on the premises, such as analog televisions.
